Sound Visualiser

A physical computing project made using Processing, Arduino and a 32×32 LED Matrix.

The requirements of the project being that there were two inputs and one output. The inputs were a push button to change between two different visualisation and serial data from a Processing sketch. The sketch performed a FFT on the given sound file and byte values taken from the FFT were passed to an Arduino Mega via Serial.

An LED Matrix was used as the output with the visualisation being drawn on the fly based on the given values. Users can either have a circular visualisation or a “bar height” visualization.
